WAs'rE-PIPE FITTING.

This invention relates to an improvement in waste pipe fittings, andmore particularly to the overflow connection leading from a bath tuberother fixture to the waste pipe. Heretofore, it has been common practiceto provide the upper end of the overflow to the waste" pipe with aflanged elbow adapted to bear againstthe outer face of a bath tub -orother-fixture, and no difficulty of a serious nature was experienced inmaking the necessary connection between this elbow and the tub where thewalls of the tub were vertical or upright or substantially so because insuch instances the "overflow pipe being vertical was practicallyparallel to the adjacent wall of the tub and the flange on the elbow waseasily placed to contact uniformly with the outer face ofthe tab. Ininstances, however, where, as is now the case with niany bath tubs andsimilar fixtures, the walls, and particularly the wall at the end of thetubv is flaring or made at an inclination, considerable diflic'ulty has7 been experienced in making this joint, and the object of my presentinvention is to provide a fitting for a waste pipe overflow to overcomethese difficulties In carrying out the invention the waste pipe overflowat the upper end thereof is preferably provided with an elbow having aball or spherical face, which, however, may be provided with a'curvedsurface of any nature and fitted with a gasket adapted to assumean offset position thereon so as to bear evenly both against the curvedsurface of the elbow and also against the outer inclined surface of thetub. I also prefer to employ a gasket retainer or a device forpreventing the radial spread of the gasket beyond a predeterminedextent, and of course the fitting includes means for maintaining theelbow in position with the gasket in place and intervening between thesame and. the outer wall of the tub, as will be hereinafter moreparticularly described.

the parts in place.

substantially spherical although as will be understood the curvature ofthe face may be varied depending upon conditions in use withoutdeparting from the nature of the invention, In the curved faced end ofthe elbow there is an inlet opening 13.

The fitting also includes a flanged retainer ring 14 and a gasket 15,.The gasket 15 is preferably triangular in cross section as illustratedin the drawing and is adapted to fit within the flanged ring retainer 14to prevent the gasket from spreading radially more than a predeterminedextent which of course is defined by the peripheral flange of the ring.a

. In the drawing the wall of a bath tubror otherfixture is designatedby: 16 andis provided with the usual'overflow opening. -My improvedfitting also includes a plate 17 adapted to extend over the overflowopening in the wall of the tub and provided with suitably spacedapertures 18 for the passage of water or other liquid, together with acentrally disposed opening 19 through which a post 20 passes to engage abar to secure As is customary, the inner end of the post 20 is screwthreaded as shown in the drawing and the outer end thereof provided withan eye 21 in which there is a ring 22 for connection with the customarystopper chain 28.

As indicated in Figs. 1 and 2, the elbow 11 interiorly is provided witha bar 24 fixed centrally with a tapped opening 25 for the reception ofthe screw threaded end of the post 20 so that when the parts areassembled and the post turned to position with the shoulder 26 on thepost bearing against the outer surface of the plate 17 the gasket willbe compressed between the curved surface of the flange, the edge of thewall defining the opening in the tub, and also preferably against theinner surface of the plate 17, the spread of the gasket being limitedradially as hereinbefore stated by the flange on the ring 14. The partsbeing thus assembled a sufficiently tight joint is made for the overflowconnection from the tub or otherfixture to the Waste pipe.

As shown in Fig.4, in some instances, particularly where the angle ofinclination of the wall of the tub is relatively great it may benecessar or advisable to so construct the elbow and t 1e cross barthereof that the cross bar will turn to accommodate itself to a positionin which the post may be readily engaged in the tapped opening in thecross bar. As illustrated in this figure, the crossbar isdesignated at27 and at the ends thereof, one end only being shown, there aretrunnions 28 adapted to engage in sockets 29 providedfor this purpose inbosses 30 on the inner surface of the elbow. In this structure, as willbe readily under stood, irrespective of the inclination of the wall ofthe tube the parts of the fitting may be assembled and connected and inso doing the cross bar will automatically adjust itself to that positionin which the post 20 may be readily turned down in the tapped opening inthe cross bar to connect and secure the parts in their assembledrelationship.

I claim as my invention: a l

1. In a waste pipe fitting, an elbow having an outer spherically roundedsurface at one end thereof, a gasket adapted to seat in any one ofvarious positions against the spherically rounded surface of the elbowtoaccomlTIOdHtGllZ-Sblf thereto and also to bear against the edgedefining an opening in an inclined wall, and devices for securing thegasket in place and preventing the same from spreading radially morethan a predetermined extent.

2. In a. waste pipe fitting, an elbow havin an outer rounded surface atone end thereo a gasket adapted to seat in] any one of various positionsagainst the rounded surface of the elbow to accommodate itself theretoand also to bear against the edge defining an opening in an inclinedwall, means for securing the gasket in place between the said wall andthe said rounded surface of the elbow, and means for preventing thegasket from spreading radially more than a predetermined extent.

3. In a waste pipe, fitting, an overflow pipe, an elbow having asubstantially spherical outer surface at one end thereof, a gasketadapted to assumeany one of various positions against the said sphericalouter surface of the elbow to accommodate itself thereto and also tobear against the edge defining an opening in an inclined wall, a plateadapted to bear against the outer surface of the said wall and to coverthe said opening therein, and meansfor simultaneously maintaining thesaid plate in posit-ion and securing the gasket in place between thesaid wall andthe spherical surface ofthe elbow. 4:. In a waste pipefitting, an overflow pipe, an elbow having a substantially sphericalouter surface at one end thereof, a gasket adapted to assume any one ofvarious positions against the said spherical outer sur face of the elbowto accommodate itself thereto andalso to bear againstthe edge definingan opening in an inclined wall, a bar extending transversely across theelbow and mounted to turn therein, a plate fitting ovcrthe opening inthesaid wall, and a pin passing through thesaidiplate and engaging the saidtransverse bar for simultaneously maintaining the plate in position; andsecuring the gasket in place between the wall and the spherical surfaceof the elbow.
